EXPLOSIVE ENGINE.

Application filed March 18, 1925. Serial No. 16,354.

thus obtaining reliability in firing the charge. A further object of myinvention is the provision in the head of an explosive engine of achamber having a partition sepa rating the inlet and exhaust ports,which communicate with the cylinder of the en gine, from each other, andseparating the spark plug from the exhaust passage leading to theexhaust port, whereby fouling of the plug contacts and of the inlet portand valve by oilland products of combustion is eliminated.

Still another object of my invention is to provide a structure of thekind described, which is simple, cheaply made, durable, not liable toget outof order, and which greatly increases the efliciency of theengine.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawing which illustrates the preferred embodimentof my invention, v

vFig. 1 is a top view, partly broken away of a head and body of anexplosive engine provided with my improvement. Fig. 2 is asideelevation, part-1y broken away, of the same.

Fig. 3 is an under view of the head having my improvement. a. M

Simllar characters Obreference designate similar parts.

1 designates the body of an explosive en-' gine of'awell known type,having in its top the usual inlet-port 2 and exhaust port 3, and theusual inlet valve 4 and exhaust valve 5 respectively controlling saidports.

6 designates the head on the top of the body 1,and which forms therewitha chamber havin a partition 7 which separates the chamber into anexplosion compartment 8 communicating with the port 2, and an exhaustcompartment 9 communicating with theexhaust port In the compartment 8located the .ignition device, which may comprise the usual spark plug 10having the usual contacts in the compartment 8 separated from theexhaust passage or compartment 9 by the partition 7. As shown in thedrawing, the. partition 7 may have an angular extension 11, which formsin the compartment 8 a corner pocket, and which" is interposed betweenthe adjacent side of the inner wall of the power cylinder 12, which isin the body 1, and the spark plug .10. As will be noted the spark plug10 is located "closely adjacent to the port 2 and in said corner pocket,so that it will reliably ignite the charge, due also to the fact that byhavmg the partition to separate the ,two compartments, the charge willbe dense and Tree from oil and products of combustion. As 75.

the angular extension Ilis at the outer side of the inner cylinder,wall, and between the latter and the spark plug 10, said extensionjwillguidethe products of combustion away "from the compartment 8andinto the exhaust compartment 9, thereby protecting the spark plugfrom contact with such products, so that the plug will keep clean for arelativel long time.

exhaust valve is open and the piston is making its exhaust stroke, therush of the burnt vapor from the cylinder to the exhaust port willswee'p from the top of the piston oil and oil vapor which will becarried out with the exhaust products into the exhaust manifold or theexhaust compartment 9. The

piston then on the intake stroke, with the inlet valve 4: open, willdraw a charge into A er the charge hasbeen fired afid'the 85 I thecompartment 8, and as the charge will be, I

free from oil or oil vapor or burnt products, it will be reliably firedby the spark plug v1O and will have a maximum ofpower.

' From the above description, it will be understood that the provisionof the partition 7 with its extension ll'extending between the explosioncompartment 8 and the inner wall of the cylinder at the outer sidethereof,

and between said inner wall and the spark plug 10, that the latter willbe, protected from deposit of burned products and will be efiicient foran extended period, and the explosive charges will be practically freedfrom contamination by the exhaust products.

It will be, of course, understood,- that the improvement abovedescribed, as associated with one cylinder, is in like manner applicableto all of the cylinders, as is illustrated in the drawing. Thedescription of one will properly applyto-each.

- I do not limit-my invention to thestructure shown and described, asmany modifications, -within the scope of th appended claims; may bemade,without departing from the spirit of my invention.

What I claim-is:=- y 1; In an explosiveengine, the combination with apower cylinder, of a chamber having therein-a partition which dividesthe chamber into an explosion compartment having an inlet port, and anexhaust compartment having an exhaust port, both of'said compartmentscommunicating with said cylin- Ider, said partition having anangularextension at the outer side of and between the inner wall of saidcylinder and said explosion compartment, andforming in the latter acorner pocket, valves respectively controlling saidports, and anignition device in tion with an engine body having a power 'cylinder anda head mounted'on the body,

of a chamber formed by the body and head having therein a partitionwhich divides the chamber. into an explosion compartment having aninletport and an exhaust compartment having an exhaust port, both of saidcompartments communicating with said cylinder, said partition having anangular extension at the outer side of and between the inner wall ofsaid cylinder and said explosion compartment, and forming in the lattera corner pocket, valves respectively controlling said ports, and'anignition device in said corner pocket.

In testimony whereof I have signed my name to this specification.
